INDICATOR AND ALARM.

Specification of Letters Patent.

Patented Mar. 4, 1913.

Application filed May 24, 1-912. Serial No. 699,426.

1'0 alt whom, it may concern.

Be it known that 1, JOHN W. SULLIVAN, a citizen of the United btates,residing at New 1' ork, in the county of New lork and State of N ewI'ork, have invented new and useful improvements in indicators andAlarms, of which the following is a specification. 'l'his inventionrelates to indicators and alarms for indicating the height of water intanks, vessels and the like and for automatically sounding an alarm whena predetermined level has been reached.

The invention has for its object to produce a device of simple andimproved construction which may be readily applied to Ships forindicating the height of water in the hold' in the event of leakage andfor sounding an alarm in ample time to givewarning if the water shouldreach the danger mark.

A further object of the invention is to produce a device of the classdescribed which shall be simple and inexpensive, easily installed andperfectly automatic in its oper-. ation.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claim.

In the accompanying drawing has been illustrateda simple andpreferred'form or the invention, it being, however,'understood that nolimitation is necessarily made to the precise structural details thereinexhibited,

' but that changes, alterations and modifications'within the scope ofthe claim may be resorted to when desired.

In the accompanying drawing,- Figure 1 is a sectional elevation showingthe improved device installed. Fig. 2 is a detail view in elevationillustrating a slight modificati'on.

Corresponding parts in .both figures are denoted b like characters ofreference.

In the hold A of a ship, adjacent to the bottom thereof, is placed aninverted bell or vessel 1 having lugs forming feet 2 whereby the loweredgeof the bell is slightly elevated above the floor to which the bellis securely connected by fastening members, such as screws 3, engagingthe floor through the lugs 2. Connected with the closed top of the belland engages one end of a trip lever 12, the

opposite end of which has a tooth l5 arranged in the path of a tripdevice, such as the wrist 14 01 a wheel 15 rorming one of a springactuated train inclosed within a casing striker 17 adapted to engage abell 1:5 for the purpose of sounding an alarm.

it is desired to be understood that the alarm device may be of anysuitable and de- 16 for the urpose of actuating the sired type andconstruction, and for the purpose of making this clear there has beenshownin Fig.2 an alarm bell 19arranged in a circuit including a battery20 and adapted to be closed by the trip lever 12 when the latter isactuated to a certain predetermined extent, thereby sounding the alarm.

It will be readily understood from the foregoing description that theimproved device may be readily installed in the hold, or

in one or more compartments of a ship and I that, in the event of aleak, the water rising within the hold or compartment and within thebell 1 will compress the air within said bell, the tube 4 and the branch8, thereby actuating the indicator 6 of the gage 5 which is to bearranged in some conveniently accessible and conspicuous place where itmay be consulted at a glance as often as may be desired. It will beunderstood that the units of the scale 7 may be taken to represent feetof water in the hold or that'other units of measurement may be adopted.The oflicers of the, ship will thus be enabled at any time to detect thepresence of water in the hold before a danger line is reached. As afurther precaution, however, the alarm device is provided which is soarranged that when the water reaches a predetermined height sufficientpressure will be created to alarm to be sounded.

Having thus described the invention, what I on the casing, and a postconnected with the is claimed as new, is diaphragm and extending throughthe cas In a device of the class described, a bell ing to actuate thetrip lever; in combination supported above the floor of a compartmentwith an alarm device actuated by the trip 5 and havingan upwardlyextending tube, a lover.
